Abstract
The invention relates to a bactericide containing tebuconazole and scutellaria baicalensis. The bactericide consists of effective ingredients, namely the tebuconazole and the scutellaria baicalensis, wherein the weight ratio of the scutellaria baicalensis to the tebuconazole is 1-6:10-50. The invention further provides application of the bactericide in prevention and control of a rice sheath blight disease. The bactericide is prepared by blending the traditional Chinese medicine scutellaria baicalensis and the bactericide ingredient. An experiment proves that after the scutellaria baicalensis is added into the bactericide ingredient, the drug resistance to the bactericide of pathogens can be reversed, accordingly the prevention and control effect of the bactericide can be improved, the cost ad residues of the bactericide can be remarkably reduced, higher economic benefits are created for farmers, and the food safety is also ensured.
Description
Technical field
The present invention relates to technical field of pesticide, specifically a kind of bactericide containing Tebuconazole and the root of large-flowered skullcap.
Background technology
Tebuconazole; chemical name is (RS)-1-(4-chlorphenyl)-4; 4-dimethyl-3-(1H-1; 2; 4 triazol-1-yl methyl) penta-3-alcohol; be a kind of efficient, wide spectrum, interior absorption triazole type sterilization pesticide, have protection, treat, root out three zones, fungicidal spectrum is wide, the lasting period is long.
Tebuconazole is used as seed treatment and foliar spray in worldwide, and fungicidal spectrum is wide, not only active high, and the lasting period is long.Tebuconazole is mainly used in preventing and treating the multiple fungal disease on the crops such as wheat, paddy rice, peanut, vegetables, banana, apple, pears and corn and Chinese sorghum, and it obtains registration and extensive use in 60 various crop of more than 50 countries in the whole world.These product are for preventing and treating sclerotinia rot of colza, and not only preventive effect is good, and have resistant to lodging, the features such as production-increasing function is obvious, be the demethylation suppressing ergosterol on its cell membrane, make germ cannot form cell membrane, thus kill germ the mechanism of action of germ.In recent years due to its large-area popularization, pathogen is caused to reduce its susceptibility, resistance grow.
Summary of the invention
The technical problem to be solved in the present invention is, for the deficiency that above-mentioned existing bactericide exists, a kind of bactericide containing Tebuconazole and the root of large-flowered skullcap is provided, overcome that existing bactericide causes due to resistance problems preventive effect reduces, consumption strengthens, residual high and defect that cost is high.
The present invention realizes the technical scheme that above-mentioned purpose takes: a kind of bactericide containing Tebuconazole and the root of large-flowered skullcap, active ingredient is made up of Tebuconazole and the root of large-flowered skullcap, and the described root of large-flowered skullcap and the weight ratio of Tebuconazole are 1-6:10-50.
The present invention's also application of claimed described bactericide on the water prevention rice sheath blight.
The present invention utilizes baikal skullcap root and microbiocidal composition mixture, test proves, add the root of large-flowered skullcap in germicide constituent after, the pesticide resistance of pathogen to bactericide can be reversed, thus improve the control efficiency of bactericide, and can significantly reduce drug cost and medicament residue, for peasant household creates higher economic benefit, also ensure that food security simultaneously.
Embodiment
Below in conjunction with test data and embodiment, technical scheme of the present invention and beneficial effect are described further.
One indoor joint toxicity measuring test
For clear and definite bactericide (propiconazole, SYP-3375, carbendazim, epoxiconazole, prochloraz, Fluoxastrobin, thifluzamide, tetraconazole, Tebuconazole, azoles alcohol, jinggangmeisu, Difenoconazole) and root of large-flowered skullcap mixture affect the virulence of Rhizoctonia solani Kuhn, mycelial growth rate method is adopted to carry out indoor measurement.
Rhizoctonia solani Kuhn is separated from surrounding area, Guigang, purifying cultivate after through Koch's Postulates verify its pathogenic after by strain inoculation in PDA medium, at 25 DEG C, under 90% damp condition, cultivate 5d, break into bacterium cake with 0.4cm card punch after mycelia covers with culture dish and use.
The root of large-flowered skullcap and bactericide are pressed active ingredient part by weight 1:10 respectively, 1:20, 1:50, 3:10, 6:10, 6:30, 6:50 mixing is made into binary built agent as mixture 1-mixture 7, bactericide single dose and mixture 1-mixture 7 are respectively diluted 7 concentration according to geometric ratio gradient from 10ppm, blank is made with clear water process, make PDA flat board, arranging without medicament is contrast, every concentration repeats 3 times, after aseptically the bacterium cake accomplished fluently being inverted in the dull and stereotyped central authorities of each process PDA, flat board is placed in 25 DEG C, cultivate under 90% damp condition, investigation result when mycelial growth diameter reaches culture dish diameter about 50%, calculate inhibiting rate, and the EC of each chemicals treatment is calculated by DPS Software of Data Statistics
50and composite co-toxicity coefficient.Because root of large-flowered skullcap single dose does not almost affect for Rhizoctonia solani Kuhn, therefore the present invention calculate composite co-toxicity coefficient time by the EC of root of large-flowered skullcap single dose
50be designated as 0, the EC of co-toxicity coefficient=composite
50the EC of/bactericide single dose
50.Statistics is as shown in the table.
As can be known from the above table: the root of large-flowered skullcap and propiconazole, SYP-3375, carbendazim, epoxiconazole, prochloraz, Fluoxastrobin, thifluzamide, tetraconazole, Tebuconazole, azoles alcohol all have obvious synergistic effect to Rhizoctonia solani Kuhn afterwards in 1-6:10-50 ratio is composite, and the root of large-flowered skullcap and jinggangmeisu, Difenoconazole be added or inhibitory action in composite rear to show Rhizoctonia solani Kuhn of 1-6:10-50 ratio.
Two field medicine effect tests
Test medicine
12 single doses: propiconazole, SYP-3375, carbendazim, epoxiconazole, prochloraz, Fluoxastrobin, thifluzamide, tetraconazole, Tebuconazole, azoles alcohol, jinggangmeisu, Difenoconazole;
12 mixed agents: be the weight ratio of 6:50 according to the root of large-flowered skullcap and bactericide, add the water extract of the root of large-flowered skullcap in above-mentioned single dose.
Test establishes 31 process altogether together with blank, and each process repeats for 3 times, Gong93Ge community, each community randomized arrangement.
Test method
By above-mentioned single dose and mixed agent even spraying, 21 days investigation rice sheath blight disease controlling results after medicine.
Result of the test
| Bactericide | Single dose preventive effect (%) | The root of large-flowered skullcap and bactericide are 6:50 mixture (%) |
| Propiconazole | 73.6 | 83.1 |
| SYP-3375 | 71.1 | 89.8 |
| Carbendazim | 66.8 | 84.2 |
| Epoxiconazole | 72.7 | 86.5 |
| Prochloraz | 67.0 | 94.2 |
| Fluoxastrobin | 69.3 | 91.6 |
| Thifluzamide | 73.3 | 87.9 |
| Tetraconazole | 73.4 | 87.7 |
| Tebuconazole | 67.2 | 87.3 |
| Azoles alcohol | 70.7 | 87.4 |
| Jinggangmeisu | 43.5 | 41.4 |
| Difenoconazole | 64.8 | 66.9 |
As can be known from the above table: the root of large-flowered skullcap and propiconazole, SYP-3375, carbendazim, epoxiconazole, prochloraz, Fluoxastrobin, thifluzamide, tetraconazole, Tebuconazole, azoles alcohol are more obvious than single dose good in the composite rear preventive effect to rice sheath blight disease of 6:50 ratio, and the root of large-flowered skullcap and jinggangmeisu, Difenoconazole are more or less the same in the composite rear preventive effect to rice sheath blight disease of 6:50 ratio and single dose.
